What does a High WebRTC Leak Risk mean for Amazon Sellers?
"WebRTC leaks can expose your real physical location, leading to account association. Learn how to detect and fix it."
The Hidden Danger of Web Real-Time Communication (WebRTC)
WebRTC is an open-source project that gives web browsers real-time communication capabilities (like video calling) without needing plugins. However, a major side-effect is that it can bypass standard VPNs to request your true, local IP address directly from your router.
Why Amazon Sellers Should Panic
Amazon uses incredibly aggressive tracking to combat policy violations and 'related accounts' (Account Association). If you use an anti-detect browser or a VPN to manage an Amazon store in the US while sitting in another country, but you fail to mask WebRTC, Amazon's backend scripts will silently ping your browser.
Your browser will then happily report the VPN's US IP, AND your real physical router IP (e.g., a local ISP from your actual country). Instantly, Amazon links this account to any other account managed from that same physical network.
How to Detect and Prevent Leaks
1. Always test your environment: Run the IPCheck.cc WebRTC Leak tool before logging into Seller Central. If it shows your real IP or a private network block, you are exposed.
2. Disable WebRTC: Most modern anti-detect browsers handle this natively. For standard browsers, you must install dedicated WebRTC blocker extensions.
3. Route traffic completely: A robust router-level proxy or a premium proxy client guarantees that no packet—not even UDP WebRTC traffic—leaks out the side door.
